Therefore, the experiment through IVECO can draw drawing a conclusion, when the vehicle that quality surpasses IVECO rolls deceleration strip with the 10km/h speed of a motor vehicle, can make the current that can flow all flow in the middle of water bag 6.
With the method for this experiment can instead release with to draw a conclusion: when the speed of a motor vehicle is the 10km left and right sides, body quality m >=vehicle of 352.8kg rolls deceleration strip and just can make and examine in the mobile whole energy storage water bags 5 of the water yield.
Can both flow under the situation of energy storage water bag 5 at the current that guarantee to flow, the relation of the car weight and the speed of a motor vehicle is following:

Confirm to flow the water yield:
Water bag 1 is wide to be 230mm, and water bag 1 is long to be 800mm, and energy storage water bag 5 is long to be 440mm, and the height of energy storage water bag 5 has restriction, is h=36mm to the maximum.
Because the height of energy storage water bag 5 has restriction, is h=36mm to the maximum, therefore, there is energy storage water bag 5 to confirm that the reliable water yield that flows is V=2.3dm * 4.4dm * 0.36dm=3.64L
After vehicle grinds, guaranteeing to have time enough is under the situation of the water backflow in the intermediate energy storage water bag 5, calculates once circuit generated energy fully:
Return time t=3.64L/ (4 * 0.119L/s)=7.6s
Power curve from Fig. 8 can know, when mean velocity is 0.119L/s, and the about 5.1w of single generator average power.So can try to achieve once complete circuit generated energy is Q=Pt=5.1w * 7.6s * 4=155.04J
Also deducibility thus, the front and back two cars time lag through deceleration strip, except the moment that deceleration strip is rolled by wheel, generator 6 was all in running order when being no more than 7.6s.When the interval of vehicle process during less than 7.6s, the current that can flow also are not able to do in time all to flow to the both sides water bag and just are forced in the energy storage water bag 5 again, begin the generating that refluxes then again.When the interval of vehicle process during greater than 7.6s, the backflow meeting stops when 7.6s, after next train rolls, just begins generating.
The relation of the voltage of generator 6, power and flow velocity such as Fig. 8.Through to the tracing analysis among water flow data and Fig. 8, draw to draw a conclusion: with the increase of flow velocity, voltage and power also increase, and the generating efficiency of generator is near the highest when mean velocity is 0.12L/s.

Pressing plate 12 is connected with spring 13.Because the variable force of spring 13 and decrement are linear relationships,
So F=4 * (0.01k+0.036k) * 1/2=24.99
Release spring [coefficient of k=223.125N/m according to the optimum value of generator 6 generating efficiencies, so get k=220N/m, the mean velocity in the generator is 0.119L/s, and the power of single generator is 5.1w under this kind operating mode.
Reflux when initial, energy storage water bag 5 is to be in when being stressed maximum, so back-flow velocity is greater than average back-flow velocity 0.12L/s, so initial back speed can make generator 6 turn round; Stop flow velocity and can not be lower than 0.0253L/s, otherwise motor can not output voltage.In the termination moment of refluxing, spring 13 decrements on the pressing plate 12 are 10mm.The termination that refluxes flow velocity constantly is following:
Termination pressure F=4 * 0.1m * 220N/m=8.8N
Termination pressure P=F/S=8.8N/ (0.44m * 0.23m)=86.957Pa

Like Fig. 6, Fig. 7; Top board 18 is equipped with return spring 17 with base plate 16 openings; Make vehicle can get back to original position through deceleration strip later top board 18, discharge water bag 1, top board 18 moves downward the extraneous minimum force that needs and can adjust through return spring 17 numbers of 16 of top board 18 and base plates.
Adjust according in kind and actual demand; In order to let Bicycles and Motorcycles wait for bus certain damping and generating effect are arranged also; Generally being adjusted into the extraneous minimum downforce that needs is 300N, promptly except the pressure of top board self, also needs 300N that top board is moved downward.
Two side guard plates of speed belt are used to protect the deceleration strip two ends, and the side end face at deceleration strip two ends is connected each other, and promptly safety is attractive in appearance again.This side guard plate directly is installed on the road surface, does not link to each other with intermediate portion.
Speed was fast when vehicle crossed, and impacted greatly, and this formula design can be stored in the water bag by the absorption portion energy, and utilizes it to generate electricity after the vehicle stone roller, reduces the impact of deceleration strip to vehicle simultaneously.Keep travelling comfort and Security by bus.
Deceleration strip is circular-arc cross-sectional outling, high h=6cm, wide d=38cm, depth-width ratio h/d=0.1578.
Got by 0.1428 * 38=5.4264, adopt the A type to widen, programmable height is h=5.4264～6cm.
